I'm not going to mince words here: if you don't have a Nexus phone, odds are pretty good that you aren't running Android 6.0. The best that you can say of most manufacturers when it comes to this software cycle is that maybe they're kinda-sorta trying to update last year's flagship phones. Sony has been a little better than most in that regard - they've already updated several phones and tablets from the Z4 and Z5 series, and now even older models are getting in on the action. According to XperiaBlog, the Xperia Z2, Xperia Z3, and Xperia Z3 Compact are being updated to Android 6.0 starting today.
Of course that's a little less impressive than it sounds, considering that the Xperia Z2 is barely two years old at this point - Sony goes through flagship phone generations like a puppy goes through expensive carpets. Also, note that your location may determine whether or not you'll get the update any time soon. The specific models that are getting the update are the Z2 D6503, Z3 D6603, and Z3 Compact D5803. That should cover unlocked phones in the US, Latin America, the Middle East, Africa, Russia, and Ukraine. (If you're seeing it somewhere else, drop us a line in the comments).
The good news is that the update is Android 6.0.1 with the February security release, so it's fairly recent as these things go. The software also includes the 2.0 version of Sony's latest camera app. XperiaBlog has a few files available for side-loading, otherwise you may be waiting a few days for an over-the-air update. If you don't have one of the compatible phone models, maybe you'll have better luck with the beta test... though considering it's six months old, I wouldn't hold my breath.
